My FW was a college graduation gift in 1973, from my parents. Since I was not a sewing person I've not used it a lot and I bought a new machine when I started quilting. I will never get rid of it and someday it will go to my daughter.
I thought maybe I had mine the longest, but I see a couple people have bet me on that.
Oh and I also own my mother's 301a which she bought new. I know they are not as popular as Featherweights, but still vintage and well-liked by their owners.
